Description

Technical Field

[0001] The utility model relates to the field of denture cutting and processing, in particular to a denture precision cutting device. Background Art

[0002] Dentures are what people often call "false teeth". In the process of denture processing and production, making impressions is one of the key steps for the success of full dentures. It needs to be completed through several steps: taking initial impressions, making individual trays, edge shaping and taking final impressions. After making impressions, they are poured into plaster models. At present, when Chinese doctors make porcelain teeth, they mostly use alginate impression materials to take impressions, copy a plaster working mold to the factory to process dentures. After the factory receives the model, it trims and cuts it before making the dentures.

[0003] The Chinese patent with patent number CN202222376949.4 discloses a denture cutting device with a protective structure, including a box body, a box cover is installed on the upper end of the box body, and a cutting machine is movably connected to the bottom of the box cover. A through groove is penetrated through the box body, and a baffle is slidably connected in the through groove. A support plate is fixedly connected to the baffle, and two clamping mechanisms are provided on the support plate. Four supporting legs are installed at the bottom of the support plate, and rollers are installed at the bottom of the four supporting legs. A dust removal mechanism is installed on the box body.

[0004] The denture cutting device described in the above patent can collect the dust generated during the cutting process while cutting the denture model, thereby avoiding a dirty environment around the denture cutting device during cutting. However, on the one hand, the denture cutting device of the above structure mainly uses manual observation to align the cutting component with the cutting baseline pre-drawn on the denture model when cutting the denture model. This may easily lead to poor accuracy in cutting the denture model due to large errors in the alignment by manual observation. On the other hand, since the angle of the denture model is mainly adjusted manually during the cutting process, this will cause the entire cutting process of the denture model to be discontinuous, increase the labor intensity and make the cutting efficiency of the denture model relatively low.

[0005] The technical problem to be solved by the utility model is to provide a denture precision cutting device which can realize automatic calibration of the cutting wheel and the denture model during cutting and automatic rotation adjustment of the angle of the denture model during the cutting process in response to the current status of the prior art.

[0006] The utility model is achieved through the following technical scheme: the utility model proposes a denture precision cutting device, including a support, a rotating motor is fixed in the middle of the top end of the support, a turntable for placing the denture model is connected to the power output shaft of the rotating motor, a side-opening cutting cover is welded on the periphery of the upper end of the support, an electric slide rail 1 is installed in the middle of the top end of the cutting cover, an electric slide rail 2 is connected to the sliding block of the electric slide rail 1, a cutting motor is connected to the sliding block of the electric slide rail 2 through an electric push rod, a cutting wheel is fixed to the power output shaft of the cutting motor through bolts, an inverted L-shaped fixing plate is fixed on the housing of the cutting motor at one side of the electric push rod, and a laser lamp is fixed to the top end of the fixing plate.

[0010] Furthermore, two clamping blocks for clamping the denture model are symmetrically arranged on both sides of the turntable in the cutting cover, and an electric telescopic rod is fixed between each clamping block and the inner wall of the cutting cover.

[0014] Furthermore, a filter screen is slidably installed in the negative pressure dust collecting box, and the air suction port of the negative pressure dust collecting box is connected to the negative pressure pump fixed on the top of the cutting cover through a pipeline.

[0015] By adopting the above technical solution, the filter plate can filter the dust-containing gas entering the negative pressure dust collecting box, so as to achieve the retention of dust inside the negative pressure dust collecting box, and the purified gas is discharged through the negative pressure pump.

[0016] Furthermore, the air suction port of the negative pressure dust collecting box is located below the filter screen plate, and the air outlet of the negative pressure dust collecting box is located above the filter screen plate.

[0018] Furthermore, a transparent baffle is installed at the opening of the cutting cover through a hinge, and the locking part on the transparent baffle and the locking part on the cutting cover are both fixed with magnetic strips.

[0023] When in use, the utility model utilizes electric slide rails 1 and 2 to achieve synchronous adjustment of the positions of the cutting wheel and the laser lamp, so that when the laser lamp contacts the side edge of the baseline on the denture model, the cutting wheel and the cutting baseline on the denture model are aligned, reducing the error caused by the alignment of the denture model with the naked eye during the cutting process, thereby improving the accuracy of the denture model cutting. At the same time, the utility model cooperates with the rotating motor and the turntable to achieve automatic adjustment of the angle of the denture model during the cutting process, eliminating the tedious operation of manual shutdown adjustment, making the entire cutting process of the denture model more continuous, thereby improving the cutting efficiency of the denture model.

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figure 1-Figure 5As shown, a denture precision cutting device in this embodiment includes a support 5, a rotating motor 6 is fixed in the middle of the top end of the support 5, and a turntable 7 for placing the denture model is connected to the power output shaft of the rotating motor 6. A side-opening cutting cover 3 is welded on the outer periphery of the upper end of the support 5, and an electric slide rail 13 is installed in the middle of the top end of the cutting cover 3. The sliding block of the electric slide rail 13 is connected to the electric slide rail 2 14, and the sliding block of the electric slide rail 2 14 is connected to the cutting motor 18 through an electric push rod 17. A cutting wheel 19 is fixed to the power output shaft of the cutting motor 18 through bolts, and an inverted L-shaped fixing plate 16 is fixed on the housing of the cutting motor 18 at one side of the electric push rod 17, and a laser lamp 21 is fixed to the top end of the fixing plate 16. The laser lamp 21 is located above the cutting wheel 19, and the irradiation light of the laser lamp 21 is parallel to the cutting surface of the cutting wheel 19.

[0033] During use, through such a design, when the laser lamp 21 is started and moves synchronously with the cutting wheel 19, when the light of the laser lamp 21 is aligned with the side of the cutting baseline on the denture model, it can ensure that the cutting wheel 19 is facing the cutting baseline on the denture model at this time, thereby realizing accurate proofreading of the position of the cutting wheel 19. During cutting, when the denture model is placed on the turntable 7, the rotating motor 6 can be used to realize automatic adjustment of the angle of the denture model during the cutting process. At the same time, the electric slide rail 13 and the electric slide rail 2 14 can be used to realize synchronous adjustment of the position of the cutting wheel 19 and the laser lamp 21, so that when the laser lamp 21 contacts the side of the baseline on the denture model, the cutting wheel 19 is aligned with the cutting baseline on the denture model, thereby reducing the error caused by the alignment of the denture model by naked eye during the cutting process, thereby improving the accuracy of the denture model cutting.

[0034] like Figure 1-Figure 3 As shown, in this embodiment, two clamping blocks 8 for clamping the denture model are symmetrically arranged on both sides of the turntable 7 in the cutting cover 3, and an electric telescopic rod 9 is fixed between each clamping block 8 and the inner wall of the cutting cover 3. When the denture model is placed on the turntable 7 and the cutting angle is adjusted, the clamping block 8 can be clamped on the denture model under the action of the electric telescopic rod 9, so as to achieve clamping and fixing of the denture model.

[0035] like Figure 1-Figure 5As shown, in this embodiment, a U-shaped dust hood 10 is installed above the electric telescopic rod 9 in the cutting hood 3, and a dust nozzle 20 is fixed at the dust suction port of the U-shaped dust hood 10. The air outlet of the U-shaped dust hood 10 is connected to the negative pressure dust collection box 1 fixed on the top of the cutting hood 3 through a pipeline. The U-shaped dust hood 10 and the dust nozzle 20 can fully absorb the dust generated in the cutting process in the cutting hood 3. A filter screen plate 2 is slidably installed in the negative pressure dust collection box 1. The air suction port of the dust box 1 is connected to the negative pressure pump 12 fixed on the top of the cutting hood 3 through a pipeline. The filter plate 2 can filter the dust-containing gas entering the negative pressure dust box 1 so as to achieve dust retention inside the negative pressure dust box 1, and the purified gas is discharged through the negative pressure pump 12. The air suction port of the negative pressure dust box 1 is located below the filter plate 2, and the air outlet of the negative pressure dust box is located above the filter plate 2, which can ensure that the filter plate 2 fully filters the dust-containing gas after inhalation.

[0036] like Figure 3-Figure 5 As shown, in this embodiment, a transparent baffle 11 is installed at the opening of the cutting cover 3 through a hinge, and the locking parts on the transparent baffle 11 and the locking parts on the cutting cover 3 are fixed with magnetic strips 15. The transparent baffle 11 can effectively block the opening of the cutting cover 3, which can facilitate the staff to control the denture model cutting process and effectively avoid the splashing of dust during the cutting process. An operation panel 4 is also connected to the middle part of the outer side wall of the cutting cover 3 by bolts. The operation panel 4 is electrically connected to the negative pressure pump 12, the rotating motor 6, the cutting motor 18, the laser lamp 21, the electric push rod 17, the electric telescopic rod 9, the electric slide rail 13 and the electric slide rail 2 14. The operation panel 4 can realize the coordinated opening and closing of the negative pressure pump 12, the rotating motor 6, the cutting motor 18, the laser lamp 21, the electric push rod 17, the electric telescopic rod 9, the electric slide rail 13 and the electric slide rail 2 14 to ensure the efficient progress of the denture model cutting process.

[0037] The specific implementation process of this embodiment is as follows: when cutting, first connect the device to an external power source, and place the denture model to be cut on the turntable 7, then drive the turntable 7 to rotate under the action of the rotating motor 6 to realize automatic adjustment of the angle of the denture model, and clamp the denture model under the action of the electric telescopic rod 9 and the clamping block 8, then only need to use the electric slide rail 13 and the electric slide rail 2 14 to realize the synchronous adjustment of the position of the cutting wheel 19 and the laser lamp 21, so that when the laser lamp 21 contacts the side of the baseline on the denture model, the cutting wheel 19 and the cutting baseline on the denture model are aligned, and the denture model can be cut while the rotating cutting wheel 19 descends. Since the angle of the denture model is automatically adjusted during the cutting process, the tedious operation of manual stop adjustment is effectively omitted, so that the cutting efficiency of the denture model is improved. At the same time, since the position calibration of the cutting wheel 19 is carried out with the assistance of the laser lamp 21, the error caused by the alignment of the denture model by naked eye observation during the cutting process is effectively reduced, so that the accuracy of the denture model cutting is improved.
